Volume X is a continuation of the journey of the Maldonado family to the Kingdom of New Mexico. It documents the Maldonado descendants of Antonio Pérez and his wife Catalina Aponte. This couple is connected to New Mexico through the marriage of their grandson Diego de Vera to María de Abendaño, granddaughter of Juan López Holguín and Catalina de Villanueva, founders of the Kingdom of New Mexico. From this marriage and the marriages of their great-granddaughters María Ortiz de Vera and Petronila de Vera (Salas), Don Antonio and Doña Catalina became the ancestors of leading New Mexicans in later generations. This volume contains not only their direct line of descent but also cousins, uncles, aunts, and in-laws. The Maldonado database has more than 5,800 names, with many of them represented here. The time period is generally from 1598 through the nineteenth century for most names, though the direct line continues to the present. Antonio Pérez is the ancestor of many people living in New Mexico today. In this volume his other descendants can trace their connections to cousins from this extended Maldonado family. Antonio Pérez and Catalina Aponte are my twelfth great-grandparents.
